The simplified form of the expression in cube root is 4a^(8/3).

To simplify the radical expression ³√64a⁸¹, we can break it down into its prime factors and simplify each factor separately.

First, let's simplify the number inside the radical, which is 64. We can write it as 2^6, since 2 multiplied by itself 6 times equals 64.

Next, let's simplify the variable inside the radical, which is a^8.

Since we are taking the cube root, we need to find the largest factor of 8 that is a perfect cube. In this case, 2^3 is the largest perfect cube factor of 8.

So, we can rewrite the expression as ³√(2^6 * 2^3 * a).

Using the property of radicals that says ³√(a * b) = ³√a * ³√b, we can simplify further.

³√(2^6 * 2^3 * a) = ²√(2^6) * ³√(2^3) * ³√a

Since ²√(2^6) is 2^3 and ³√(2^3) is 2, we can simplify even more.

2^3 * 2 * ³√a = 8 * 2 * ³√a = 16 * ³√a

Therefore, the simplified radical expression ³√64a⁸¹ is equal to 16 * ³√a.

In summary, to simplify the expression ³√64a⁸¹, we first broke down the number 64 into its prime factors and found the largest perfect cube factor of the exponent 8.

We then used the property of radicals to simplify the expression and arrived at the final answer of 16 * ³√a.

The solution to the initial value problem is y(t)  = [tex]2e^(-5t) + 4e^(-17t)[/tex].

To solve the given initial value problem using the Laplace transform, we'll follow these steps:

Take the Laplace transform of both sides of the differential equation using the linearity property and the derivatives property of the Laplace transform.

Solve for the Laplace transform of the unknown function, denoted as Y(s).

Apply the initial conditions to find the values of the Laplace transform at s=0.

Inverse Laplace transform Y(s) to obtain the solution y(t).

Let's solve the initial value problem:

Step 1:

Taking the Laplace transform of the differential equation, we have:

s²Y(s) - sy(0) - y'(0) - 12(sY(s) - y(0)) + 85Y(s) = 0

Step 2:

Simplifying the equation and isolating Y(s), we get:

(s² + 12s + 85)Y(s) = s(6) + 58 + 12(6)

Y(s) = (6s + 130) / (s² + 12s + 85)

Step 3:

Applying the initial conditions, we have:

Y(0) = (6(0) + 130) / (0² + 12(0) + 85) = 130 / 85

Step 4:

Inverse Laplace transforming Y(s), we can use partial fraction decomposition or the table of Laplace transforms to find the inverse Laplace transform. In this case, we'll use partial fraction decomposition:

Y(s) = (6s + 130) / (s² + 12s + 85)

= (6s + 130) / [(s + 5)(s + 17)]

Using partial fraction decomposition, we can write:

Y(s) = A / (s + 5) + B / (s + 17)

Multiplying both sides by (s + 5)(s + 17), we get:

6s + 130 = A(s + 17) + B(s + 5)

Expanding and equating coefficients, we have:

6 = 17A + 5B

130 = 5A + 17B

Solving these equations simultaneously, we find A = 2 and B = 4.

Therefore, Y(s) = 2 / (s + 5) + 4 / (s + 17)

Taking the inverse Laplace transform

y(t) = [tex]2e^(-5t) + 4e^(-17t)[/tex].

So the solution to the initial value problem is y(t)  = [tex]2e^(-5t) + 4e^(-17t)[/tex].

The solution to the equation 4x + [3 -7 9] = [-3 11 5 -7] is x = [-3/2 9/2 -1 -7/4].

To solve the equation 4x + [3 -7 9] = [-3 11 5 -7], we need to isolate the variable x.

Given:

4x + [3 -7 9] = [-3 11 5 -7]

First, let's subtract [3 -7 9] from both sides of the equation:

4x + [3 -7 9] - [3 -7 9] = [-3 11 5 -7] - [3 -7 9]

This simplifies to:

4x = [-3 11 5 -7] - [3 -7 9]

Subtracting the corresponding elements, we have:

4x = [-3-3 11-(-7) 5-9 -7]

Simplifying further:

4x = [-6 18 -4 -7]

Now, divide both sides of the equation by 4 to solve for x:

4x/4 = [-6 18 -4 -7]/4

This gives us:

x = [-6/4 18/4 -4/4 -7/4]

For a polynomial f(x) with a positive leading coefficient, it can be shown that there exists a value N such that f(x) is always greater than zero for all x greater than N.

Consider the polynomial f(x) = anx^k + ... + a₁x + ao, where an is the leading coefficient and k is the degree of the polynomial. Since an > 0, the polynomial has a positive leading coefficient.

To show that there exists a value N such that f(x) > 0 for all x > N, we need to prove that as x approaches infinity, f(x) also approaches infinity. This can be done by considering the highest degree term in the polynomial, anx^k, as x becomes large.

Since an > 0 and x^k dominates the other terms for large x, the polynomial f(x) becomes dominated by the term anx^k. As x increases, the term anx^k becomes arbitrarily large and positive, ensuring that f(x) also becomes arbitrarily large and positive.

Therefore, by choosing a sufficiently large value N, we can guarantee that f(x) > 0 for all x > N, as the polynomial grows without bound as x approaches infinity.

1.10, 2.2821 7.13 31 is an absolute pseudoprime.

1.) Fermat's little theorem states that for a prime number p and any integer a, a^(p-1) ≡ 1 (mod p). If we use p = 23, we get a^(22) ≡ 1 (mod 23).Now, we know that (10^k) ≡ (-1)^(k+1) (mod 11).

Therefore, we can split 1599999999 into 1500000000 + 99999999 = 15 * 10^8 + 99999999.Using the formula, 10^22 ≡ (-1)^23 (mod 23) => 10^22 ≡ -1 (mod 23) => 10^44 ≡ 1 (mod 23) => (10^22)^2 ≡ 1 (mod 23)

Also, 10^8 ≡ 1 (mod 23).

Therefore, we have 15 * (10^22)^8 * 10^8 + 99999999 ≡ 15 * 1 * 1 + 99999999 ≡ 10 (mod 23).

Hence, the remainder when 15999,999,999 is divided by 23 is 10.

2.)A positive integer n is an absolute pseudoprime to the base a if it is composite but satisfies the congruence a^(n-1) ≡ 1 (mod n).2821 7.13 31 => 2821 * 7 * 13 * 31.

Let's verify if 2821 is an absolute pseudoprime.2820 = 2^2 * 3 * 5 * 47

Let a = 2, then we need to verify that 2^2820 ≡ 1 (mod 2821)

Using the binary exponentiation method,

2^2 = 4, 2^4 = 16, 2^8 ≡ 256 (mod 2821), 2^16 ≡ 2323 (mod 2821), 2^32 ≡ 2223 (mod 2821), 2^64 ≡ 1 (mod 2821), 2^128 ≡ 1 (mod 2821), 2^256 ≡ 1 (mod 2821), 2^2816 ≡ 1 (mod 2821)

Therefore, 2^2820 ≡ (2^2816 * 2^4) ≡ (1 * 16) ≡ 1 (mod 2821)

Hence, 2821 is an absolute pseudoprime. Similarly, we can verify for 7, 13 and 31.

By solving the system of equations and checking the solutions, we can determine if S is linearly independent and if it spans P₂.

a) To determine if the function f(t) = t² - t - 1 is in the span of S = {f₁, f₂, f₃}, we need to check if we can find scalars a, b, and c such that f(t) = af₁(t) + bf₂(t) + cf₃(t).

Let's set up the equation:

f(t) = a(f₁(t)) + b(f₂(t)) + c(f₃(t))

f(t) = a(t² - 2t - 3) + b(t² - 4t - 2) + c(t² + 2t - 5)

f(t) = (a + b + c)t² + (-2a - 4b + 2c)t + (-3a - 2b - 5c)

For f(t) to be in the span of S, the coefficients of t², t, and the constant term in the above equation should match the coefficients of t², t, and the constant term in f(t).

Comparing the coefficients, we get the following system of equations:

a + b + c = 1

-2a - 4b + 2c = -1

-3a - 2b - 5c = -1

By solving this system of equations, we can find the values of a, b, and c. If a solution exists, then f(t) is in the span of S.

b) To determine if S = {f₁, f₂, f₃} is a set of linearly independent functions, we need to check if the only solution to the equation a₁f₁(t) + a₂f₂(t) + a₃f₃(t) = 0 is when a₁ = a₂ = a₃ = 0.

Let's set up the equation:

a₁f₁(t) + a₂f₂(t) + a₃f₃(t) = 0

a₁(t² - 2t - 3) + a₂(t² - 4t - 2) + a₃(t² + 2t - 5) = 0

(a₁ + a₂ + a₃)t² + (-2a₁ - 4a₂ + 2a₃)t + (-3a₁ - 2a₂ - 5a₃) = 0

For S to be linearly independent, the only solution to the above equation should be a₁ = a₂ = a₃ = 0.

To check if S spans P₂, we need to see if every polynomial of degree 2 can be expressed as a linear combination of the functions in S. If the only solution to the equation a₁f₁(t) + a₂f₂(t) + a₃f₃(t) = p(t) is when a₁ = a₂ = a₃ = 0, then S spans P₂.

We are to find the expressions for (t⋅s)(x) and (t−s)(x) and evaluate (t+s)(3).

(t.s)(x) = t(x)·s(x)

= (x+1)(4x+2)

= 4x² + 6x + 2

(t-s)(x) = t(x) - s(x)

= (x+1) - (4x+2)

= -3x -1(t+s)(3)

= t(3) + s(3)

= (3+1) + (4(3)+2)

= 16

Therefore, (t.s)(x) = 4x² + 6x + 2,

(t-s)(x) = -3x -1, and (t+s)(3) = 16.

Explanation:

To find (t.s)(x), we need to perform the following operations:

We substitute s(x) = 4x + 2 and t(x) = x + 1 to (t.s)(x) = t(x)·s(x) (x+1)(4x+2) = 4x² + 6x + 2

Therefore, (t.s)(x) = 4x² + 6x + 2

To find (t-s)(x), we need to perform the following operations:

We substitute s(x) = 4x + 2 and t(x) = x + 1 to

(t-s)(x) = t(x) - s(x)(x+1) - (4x+2)

= -3x -1

Therefore, (t-s)(x) = -3x -1

To find (t+s)(3), we need to perform the following operations:

We substitute

s(3) = 4(3) + 2

= 14 and

t(3) = 3 + 1

We have shown that the ellipse and hyperbola intersect at right angles.

To show that the ellipse and hyperbola intersect at right angles, we need to prove that their tangent lines at the point of intersection are perpendicular.

Let's first find the equations of the ellipse and hyperbola:

Ellipse: x^2/a^2 + 2y^2 = 1   ...(1)

Hyperbola: x^2/a^2 - 2y^2 = 1   ...(2)

To find the point(s) of intersection, we can solve the system of equations formed by (1) and (2). Subtracting equation (2) from equation (1), we have:

2y^2 - (-2y^2) = 0

4y^2 = 0

y^2 = 0

y = 0

Substituting y = 0 into equation (1), we can solve for x:

x^2/a^2 = 1

x^2 = a^2

x = ± a

So, the points of intersection are (a, 0) and (-a, 0).

To find the tangent lines at these points, we need to differentiate the equations of the ellipse and hyperbola with respect to x:

Differentiating equation (1) implicitly:

2x/a^2 + 4y * (dy/dx) = 0

dy/dx = -x / (2y)

Differentiating equation (2) implicitly:

2x/a^2 - 4y * (dy/dx) = 0

dy/dx = x / (2y)

Now, let's evaluate the slopes of the tangent lines at the points (a, 0) and (-a, 0) by substituting these values into the derivatives we found:

At (a, 0):

dy/dx = -a / (2 * 0) = undefined (vertical tangent)

At (-a, 0):

dy/dx = -(-a) / (2 * 0) = undefined (vertical tangent)

Since the slopes of the tangent lines at both points are undefined (vertical), they are perpendicular to the x-axis.

Let's use the backward substitution method to solve the recurrence relation. In the backward substitution method, we start from the value of an and use the relation an = 9an - 1 to calculate an - 1, then use an - 1 = 9an - 2 to calculate an - 2, and so on until we reach the given initial value.

Here, a1 = -6, so we can start with a2. Using the relation an = 9an - 1, we get:

a2 = 9a1 = 9(-6) = -54

Using the relation an = 9 an - 1, we get:

a3 = 9a2 = 9(-54) = -486

Using the relation an = 9an - 1, we get:

a4 = 9a3 = 9(-486) = -4374

Similarly, we can calculate a5:

PV = Present value (Loan amount)

PMT = Monthly payment

r = rate per month

n = total number of months

PMT = $750

r = 4.9% per annum / 12 months = 0.407% per month

n = 48 months

Putting the given values in the loan formula, we get:

PV = $750 * [{1 - (1 / (1 + 0.00407)^48)} / 0.00407]

PV ≈ $32,631 (rounded off to the nearest dollar)

Therefore, This extension's loan amount is roughly $32,631. The correct answer is option (A) $32,631.

a) The graph originates at the origin( 0, 0) and spirals in exterior as θ increases. b) The graph have two loops centered at the origin. c) The graph is a cardioid. d) The  graph has bigger loop at origin and the innner loop inside it.. e) The graph is helical that starts at the point( 1, 0) and moves in inward direction towards the origin.

a) The function with polar equals is given by dy = θ/( 4π) with 0< θ< 4.

We've to find the crossroad points with θ = 0 and θ = π/ 2,

When θ = 0

dy = 0/( 4π) = 0

therefore, when θ = 0, the function intersects the origin( 0, 0).

Now, θ = π/ 2

dy = ( π/ 2)/( 4π) = 1/( 8)

thus, when θ = π/ 2, the polar function intersects the y- axis at( 0,1/8).

b) The polar function is given by r = sin( 2θ).

We've to find the corners with θ = 0 and θ = π/ 2,

When θ = 0

r = sin( 2 * 0) = sin( 0) = 0

thus, when θ = 0, the polar function intersects the origin( 0, 0).

Now, θ = π/ 2

r = sin( 2 *( π/ 2)) = sin( π) = 0

thus, when θ = π/ 2, the polar function also intersects the origin( 0, 0).

c) The polar function is given by r = 1 cos( θ).

To find the corners with θ = 0 and θ = π/ 2,

At θ = 0

r = 1 cos( 0) = 1 1 = 2

thus, when θ = 0, the polar function intersects thex-axis at( 2, 0).

At θ = π/ 2

r = 1 cos( π/ 2) = 1 0 = 1

thus, when θ = π/ 2, the polar function intersects the circle centered at( 0, 0) with compass 1 at( 1, π/ 2).

d) The polar function is given by r = 1- cos( 2θ).

To find the corners with θ = 0 and θ = π/ 2

At θ = 0

r = 1- cos( 2 * 0) = 1- cos( 0) = 0

thus, when θ = 0, the polar function intersects the origin( 0, 0).

At θ = π/ 2

r = 1- cos( 2 *( π/ 2)) = 1- cos( π) = 2

therefore, when θ = π/ 2, the polar function intersects the loop centered at( 0, 0) with compass 2 at( 2, π/ 2).

e) The polar function is given by r = 1- 2sin( θ).

To find the point of intersection with θ = 0 and θ = π/ 2,

When θ = 0

r = 1- 2sin( 0) = 1- 2( 0) = 1

thus, when θ = 0, the polar function intersects the circle centered at( 0, 0) with compass 1 at( 1, 0).

When θ = π/ 2

r = 1- 2sin( π/ 2) = 1- 2( 1) = -1

thus, when θ = π/ 2, the polar function intersects the negative y-axis at( 0,-1).

The exact area A of the region bounded between the curve f(x) = 1 - ln(x) and the line g(x) = 1 over the interval [1, 5] is given by:

A = -5ln(5) + 5 units²

To find the area A of the region bounded between the curve f(x) = 1 - ln(x) and the line g(x) = 1 over the interval [1, 5], we can integrate the difference between the two functions over that interval.

A = ∫[1, 5] (f(x) - g(x)) dx

First, let's find the difference between the two functions:

f(x) - g(x) = (1 - ln(x)) - 1 = -ln(x)

Now, we can integrate -ln(x) over the interval [1, 5]:

A = ∫[1, 5] -ln(x) dx

To integrate -ln(x), we can use the properties of logarithmic functions:

A = [-xln(x) + x] evaluated from 1 to 5

A = [-5ln(5) + 5] - [-1ln(1) + 1]

Since ln(1) = 0, the second term on the right side becomes 0:

A = -5ln(5) + 5

The solution of the given differential equation when y(1) = 2e²-e³ and y(0)=1 is given by   y = (1/6)e² + (2/3)e-³

Differential equation is y" + y' - 6y = 0

To show that y = Ae²+ Be-³x is the general solution of the given differential equation, first, we need to find the derivatives of y.

Now,y = Ae²+ Be-³x

Differentiating w.r.t 'x' , we get y' = 2Ae² - 3Be-³x

Differentiating again w.r.t 'x', we get y" = 4Ae² + 9Be-³x

On substituting the derivatives of y in the given differential equation, we get4Ae² + 9Be-³x + (2Ae² - 3Be-³x) - 6(Ae²+ Be-³x) = 0

Simplifying this expression, we getA(6e² - 1)e² + B(3e³ - 2)e-³x = 0

Since this equation should hold for all values of x, we have two possibilities either

A(6 e² - 1) = 0 and

B(3 e³ - 2) = 0or

6 e² - 1 = 0 and

3 e³ - 2 = 0i.e.,

either A = 0 and B = 0 or A = 1/6 and B = 2/3

So, the general solution of the given differential equation is given by

y = A e²+ B e-³x

where A and B are constants, A = 1/6 and B = 2/3

On substituting the given initial conditions, we get

y(1) = 2e²-e³

Ae²+ B e-³y(0) = 1

= Ae²+ Be-³x

Putting A = 1/6 and B = 2/3, we get

2e²-e³ = (1/6)e² + (2/3)e-³And,

1 = (1/6) + (2/3)

Therefore, the solution of the given differential equation when y(1) = 2e²-e³ and y(0)=1 is given by   y = (1/6)e² + (2/3)e-³

The set S is a vector space.

To determine if S is a vector space, we need to check if it satisfies the ten properties of a vector space.

1. The zero vector exists: In this case, the zero vector would be the function y(x) = 0, which satisfies the differential equation y'' + 2y' - y = 0, since the derivative of the zero function is also zero.

2. Closure under addition: If f(x) and g(x) are both functions satisfying the differential equation y'' + 2y' - y = sin(x), then their sum h(x) = f(x) + g(x) also satisfies the same differential equation. This can be verified by taking the second derivative of h(x), multiplying by 2, and subtracting h(x) to check if it equals sin(x).

3. Closure under scalar multiplication: If f(x) is a function satisfying the differential equation y'' + 2y' - y = sin(x), and c is a scalar, then the function g(x) = c * f(x) also satisfies the same differential equation. This can be verified by taking the second derivative of g(x), multiplying by 2, and subtracting g(x) to check if it equals sin(x).

4. Associativity of addition: (f(x) + g(x)) + h(x) = f(x) + (g(x) + h(x))

5. Commutativity of addition: f(x) + g(x) = g(x) + f(x)

6. Additive identity: There exists a function 0(x) such that f(x) + 0(x) = f(x) for all functions f(x) satisfying the differential equation.

7. Additive inverse: For every function f(x) satisfying the differential equation, there exists a function -f(x) such that f(x) + (-f(x)) = 0(x).

8. Distributivity of scalar multiplication over vector addition: c * (f(x) + g(x)) = c * f(x) + c * g(x)

9. Distributivity of scalar multiplication over scalar addition: (c + d) * f(x) = c * f(x) + d * f(x)

10. Scalar multiplication identity: 1 * f(x) = f(x)

By verifying that all these properties hold, we can conclude that the set S is indeed a vector space.

a. There are 10 choices for each digit and 26 choices for each letter, so the number of different license plates possible without repetition is 10 * 10 * 10 * 10 * 26 * 26 * 26 * 26 = 456,976,000.

b. With repetition allowed, there are still 10 choices for each digit and 26 choices for each letter. Since repetition is permitted, each digit and letter can be chosen independently, so the total number of different license plates possible is 10^4 * 26^4 = 45,697,600.

In part (a), where repetition is not allowed, we consider each position on the license plate separately. For the four digits, there are 10 choices (0-9) for each position. Similarly, for the four letters, there are 26 choices (A-Z) for each position. Therefore, we multiply the number of choices for each position to find the total number of different license plates possible without repetition.

In part (b), where repetition is permitted, the choices for each position are still the same. However, since repetition is allowed, each position can independently have any of the 10 digits or any of the 26 letters. We raise the number of choices for each position to the power of the number of positions to find the total number of different license plates possible.

It's important to note that the above calculations assume that the order of the digits and letters on the license plate matters. If the order does not matter, such as when considering combinations instead of permutations, the number of possible license plates would be different.

The sample space for a roll of a 5-sided die is {1, 2, 3, 4, 5}.

In probability theory, the sample space refers to the set of all possible outcomes of an experiment. In this case, we are rolling a 5-sided die, which means there are 5 possible outcomes. The outcomes are represented by the numbers 1, 2, 3, 4, and 5, as these are the numbers that can appear on the faces of the die. Thus, the sample space for this experiment can be expressed as {1, 2, 3, 4, 5}.

It is important to note that each outcome in the sample space is mutually exclusive, meaning that only one outcome can occur on a single roll of the die. Additionally, the outcomes are collectively exhaustive, as they encompass all the possible results of the experiment. By identifying the sample space, we can analyze and calculate probabilities associated with different events or combinations of outcomes.
